Closed weights Meta AI 564M parameters December 2021

No estimate

No hardware requirements for this model

The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.

On record

Full specification

Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

Size

How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.

Parameters
564M

XGLM-564M is a multilingual autoregressive language model (with 564 million parameters) trained on a balanced corpus of a diverse set of 30 languages totaling 500 billion sub-tokens.

What the numbers mean

Where it came from

XGLM was published by Meta AI, in United States of America, in December 2021. The organisation is categorised as industry.

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

Answers

XGLM — common questions

01

Is XGLM open source?

The licensing for XGLM was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

02

How many parameters does XGLM have?

XGLM has 564M parameters. XGLM-564M is a multilingual autoregressive language model (with 564 million parameters) trained on a balanced corpus of a diverse set of 30 languages totaling 500 billion sub-tokens. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.

03

Who created XGLM?

XGLM was published by Meta AI, based in United States of America, categorised as industry.

04

When was XGLM released?

XGLM was published in December 2021. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

05

What GPU do I need to run XGLM?

None. XGLM is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
